Hello,

I am trying to create a ruler for an image that changes along with the zoom event of the interactorstyle.
I tried using the vtkLegendScaleActor.What i am trying to achieve is marked in the pictures below. Could anyone please provide some ideas on how this can be accomplished? 

Thanks in Advance
